Good question. The movement is all natural. I tried as much as possible to avoid changing my behavior because I was recording my location. I wanted to get an objective picture of where I had been.

One exception was at Stanford during WhereCamp, I walked around a park and spelled "Where"! http://www.flickr.com/photos/aaronpk/6983337983/in/pool-1772...
